Use this Apothem of a Regular Polygon Calculator to calculate the apothem of any regular polygon using the regular polygon apothem formula and calculate polygon apothem.
This regular polygon apothem formula allows you to calculate polygon apothem accurately for any regular polygon.
| Number of Sides (n) | Side Length (a) | Apothem |
|---|---|---|
| 3 | 10 | 2.886751 |
| 4 | 10 | 5.000000 |
| 5 | 10 | 6.881910 |
| 6 | 10 | 8.660254 |
| 8 | 10 | 12.071068 |
To manually calculate polygon apothem:
1. Take the side length (a) and number of sides (n).
2. Compute π / n.
3. Take the tangent of π / n.
4. Divide a by 2 × tan(π / n) to get the apothem.
This Apothem of a Regular Polygon Calculator calculates the apothem with up to six decimal places using the regular polygon apothem formula.
It is useful for students, designers, and engineers learning polygon geometry.
• The apothem is the distance from the center to the midpoint of a side.
• Apothem is used to calculate the area of a regular polygon.
• Larger polygons have longer apothems for the same side length.
• Apothem is perpendicular to each side of the polygon.
• It is widely used in architecture and tiling calculations.
